. To all 'whom it may concern:

Be it known that ll, Louis Sonwanrzenno, a citizen of the United States,residing. at

l Chicago, in the county of Cook and State dispensed,a dozen toaofllllinois, have Ainvented a new and useful lmprovement in aCellularCarton, of which thefollowing is a specification.

' 'My' present invention relates to cartons and. similar receptacleaandmore part1cularly to a. structure of this character that is usuallylemployed .in connection with the packagin lof eg sfor the retailmarket.A

One o vthe o jects of my invention is the provision of a carton having acellular interior so that the eggs or ot er articles placed therein willbe separated. from each` other, and may be conveniently handled or usualpractice in oceries, markets, etc. Another obyect 1s t ewprovislon of acar-` single piece ofmaterial so that'the blanks which are to be foldedand formed into .the cartons may be rapidlymade lin large quantities andmay beiconveniently stored in dat condition rior to assembly. .A stillfurtherA object resides. in the provision of a cellular carton that maybe lcollapsed or folded fiat prior to being used for the dispensing ofthe articles so that a large quantity of the assembled struc-tures maybe'. collapsed and packed away ina relative small space for oth shipmentand storage. lln this connection, ll haveprovided means for. simultanef.ously movin all the transverse cell walls to their vertica positions andfor maintaining them 1n such osltion while the carton 1s 1n use. l havea so provided vend walls that aro hinged to one of the bod wallsof theassem led carton that are a apted to be moved to a position in averticalplane transverse to` the plane ofthe body wallsand there engagedwith elements projectin opposite longitudinal wa ls to maintain said4end walls against lateral movement outside ll prefer to" carry out myinvention in subpackage as is the from one of the stantially the.manner'hereinafter described,

.and as more particularly pointed ont `in the claims.

Reference will now befmade to the accomttrrttt -panying drawings thatform a part of this specification, inwhich-f Figfl is a erspective of mycarton, with 'the .cover un ocked and raised to disclose the interiorconstruction when in use. l

"left hand ends of'cartons of diderent as semblies, showing divers modesof folding .the blank for' forming the body or outside "walls, thedividing .partitions andthe cover, 'l

and several methods of assembling the same.

'The drawings illustrate typical embodiments of my invention, and byreferring to Fig. 1, which is the preferred form, it will be seen thebody of the carton, when /opened and ready foruse, comprises longi-4tudinally elonggated vertical front and rear walls A' and respectively;a bottom@ 'edges of said front and rear walls. Extending from backl wallB isa cover E that is hinged theretoqby forming a score or bend e at thejuncture'between the members .so that-the cover. may be folded downabove top wall D of the body in the usual manner of zellular eggcartons. `Extending along the front longitudinal edge of the viewshowing ltd "connecting the lower edges. thereof, and a @topmember orwall D connecting the upper cover is an extension or lap'F that isfolded down or laterally. tothe-cover, andfrom the outer edge of whichproject hooksha ed f that are adapted, w en/` locking members the coverislowered into position to -close' the carton, to engagecoactingportions of top wall D, as w1ll hereinafter moreffully may `beformed integrally with bottom C byx Y formed by in the blank uponeachside of flanges 15 and lfront of the carton,

1 pieces 16 extending 'r and said partition,

appear.

Formed integrally with top wall D in, the preferred structure, is acenter partition G that is 1formed 'from intermediate port1ons of thetop wall and is 'made by irst providing upturned flanges 15 at thecenter of width of the top wall portion of the blank and then bendingthe material between these flanges downwardly to provide paralleldownwardly to bottom C. If desired, however, partition G may be aseparate pieceof material G', as illustrated inFi s, 10 and 12 of, thedrawings, the upper ed nel formed by the upwardly extending flanges 15of the top or wall D, and secured thereto in any suitable manner,preferably y staples, or cement; or" the said partition foldingupwardlyan intermediate portion G2, of the bottom wall portion loftheblank as villustrated in Fig. l of the drawings, 1n

which latter event the lower portion of pieces Gr2 may be. securedtogether adjacent bottom wall C and the upper edge is insertedin agroove or channel formed by flanges 15 -in theitop wall7 similar to thestructure shown in Figs. 10 and 12. The artition G extendslongitudinally of the bo yof the carton so as to divide the interiorinto two similarly shaped side by side longitudinal compartments, one tothe front and one to the rear, when in vertical position. or transverseto the top and bottom walls, stiffens the structure and assistsinmaintaining the rectangular or boxlike -forln of the carton. The'transverse walls that divide the interior of the carton intocells aremaking irregularly shaped outs extending to, respectively, the front andrear walls so that suitable flaps 17 are provided that are adaptedto be,moved down to approximately thebottom C and thus divide Athelongitudinal compartments into substantially cube shaped cells, arrangedin longitudinal rows 'upon each side of central partition Gr.v Thecuts'r to form'these` cellv walls or flaps 17 are, preferably ofoctagonal shape upon the left hand half so that triangular shaped cornerconnections 18 remain in the top wall when the cell walls have beenvmoved downwardly into position,

and the diagonal or obhque edgesofth ese corner pieces 18 at connect thecell walls with the adjacentfbody wall A, and at the front of the cartonthese corner lpieces pro- '.v1de means for engaging hooks f on thelocking flange of the cover when the latter is lowered intoV positionfor closing the carton.

,As seen in Fi s. lower portions o pullstring 19, the endor-loopedportion 20 tom member ge thereof being inserted in the chan`` article inthe end cell.

along the edges pieces 18 heretofore mentioned with 3 and 4, I connectthe- 'cell'walls' o-r flapsv 17,-by a- .of which, when -the cell wallshave been drawn to their `vertical position, is slipped over theadjacent orl right hand end of flanges 15 that extend above the topwall, asseen in Figs. 4 and 5. The ends walls 21 o f the carton areprovided lby utilizingthe -cell walls at the right hand. end, and inthis connection, I form extensions 22 from bottom C that are folded overupon said botat the right hand end, vwhich extensions have upstandingflanges 23 that provide means against which the lower portion of the endcell wall 21 will engage and thereby prevent its being forced out of thecarton and'cause the' loss of the egg, or other Whenf' the carton iscollapsed, in the manner shown in Fig. 6, this end cell wall 2 1 willfold u opening in the top wall from whic cell wall 421 is formed, andthe upstand'ing piece 32 is by pasting, stapling or otherwise. These'endwalls 25 are provided .each with a diagonalifold 27 extending from theupper -rear corner to the lower front corner, as seen-in'Fig. 1, and indotted lines in Fig. 2 so that when. the carton is collapsed these endwalls 25 at the left hand end of into the aiv which flanges are secured.to their respective A'longitudinal walls in any4 -suitablef manner,

thecarton may be bent outwardly along the diagonal folds 27 in themanner shown in Figs. 3 and 6 of the-drawings, wall D and frontwall Awill be disposed substantially flat adjacent the back and bottom walls,as shown in Fig. 6.

Inorder to provide 'the diagonal portionsl of vtriangular semicircularserrations 28 that extend into'thc upper. portions of the individualcells so so that top 4provide means for. retainingl eggs olf-differentslzes 1n the carton, I may that when a small egg isinsertedinto a cellthe upper portions will engage -the outer edges lof the serrations, butwhen an egg of large diameter is inserted the serrations will bend over,more or less, downwardly so that the remaining edges of the diagonal ortriangular corner piec'eswill4 engage the upper portion of the egg andmaintainit inposition.

. Asseen in Figs.`-8 to 12, top E may be formed either as a continuationof the bacl; or rear wall' B, as seen in Figs. 8 to 11, or it may beformed from the upstanding portion :lfm

rainer l@ or thetop wall, in which eventvwall B is extended upwardly tothe'heightor artition Gr or G'- and upstanding portion ',is securedadjacent the upper edge or the back wall. Also it will be noted from theabove` mentioned figures that top wall D may be secured to the cover orto the bach wall, orinay have a dep'endiiig extension D that terminatesatv its lower edge in a lateralpieceDf that 'extends along the ad'acentportionor u.bottom C, as illustratedin Fig. 9 of the drawings, and issecured thereto in anysuitable manner. lin this-latter-event, it isunnecessaryvto secure back wall B .to the der pending extension D2unless so desired.
